Hannah is 2 times her sister’s age. The sum of their ages is no more than 18 years. 1) Write an inequality that can be used to r

svetoff [14.1K]

Answer:

1) $x+2x\leq 18$ .

2) $6$ years

Step-by-step explanation:

Let Hanna's sister be $x$ years old.

Then Hanna will be $2x$ years old.

The sum of their ages will be $x+2x$ years.

The statement "no more than 18" means the sum of their ages is less than or equal to 18.

The required inequality is;

$x+2x\leq 18$ .

The inequality we just found is

$x+2x\leq18$ .

We simplify to get;

$3x\leq 18$ .

we divide both sides by $3$ to get;

$x\leq 6$ .

Therefore the oldest age Hannah's sister can be is $6$ years

if trapezoid ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A’lie

maria [59]

Answer:

<em>Answer: (second option) (-4,1)</em>

Step-by-step explanation:

<u>Transformations of Points and Shapes</u>

The image shows a trapezoid ABCD where point A has coordinates (-4,1).

The following transformations are performed:

Reflection over the y-axis: If a point (x,y) is reflected over the y-axis, it becomes (-x,y). Thus point A becomes A'=(4,1)

Reflection over the x-axis: If a point (x,y) is reflected over the x-axis, it becomes (x,-y). Thus point A' becomes A''=(4,-1)

Rotation 180°: If a point (x,y) is rotated 180°, it becomes (-x,-y). Thus point A'' becomes A'''=(-4,1)

Answer: (second option) (-4,1)

Someone please help i will rate! :(

What you will want to do is replace x with the amount of customers so it would be 42 squared divided by 3025-55x42 which should hopefully give you your answer which is 2.339 but you may have to round it as you can’t have 1/3 of a person etc hope this helps, let me know if I’m wrong
